Ancient Egyptian princesses were buried with bows, arrows, daggers and maces, and their bones prove they actually used them.

The princesses were sisters and daughters of Pharaoh Amenemhat II and lived around 1850 to 1700 BCE. They were buried in the Dahshur royal complex in Egypt.

Their remains were first dug up in the 1890s. They were lost and then found again in 2020 inside the Egyptian Museum.

For a long time, weapons in these graves were seen as symbols. Weapons were usually linked to male burials.

The bones tell a different story. The researchers found strong development in the upper arms, linked to repeated, powerful movements like pulling a bowstring. Princess Itaweret's skeleton showed patterns of skilled archery practice. All of them had strong muscle attachment marks from regular hard physical activity.

Several had healed injuries, including broken ribs and foot fractures. Because the bones healed well, they likely had access to good medical care.

They were royal women who trained with weapons, not just carried them to the grave.

Scientists found traces of two human ancestors that no one has ever found a fossil of, and they are hidden in your DNA.

Researchers at UC Berkeley built a new method called TRACE. Instead of digging for bones, it looks for patterns in the genomes of people alive today to find DNA that came from unknown lineages.

They found two "ghost" ancestors.

The first one interbred with early humans in Africa more than 50,000 years ago. It split from our ancestors about 800,000 years ago. Today, people carry roughly 0.5 to 1% of their DNA from it, in both African and non-African populations, so it likely shows up in people all over the world.

The second is even older. It came from a lineage dating back about 1.8 million years. It interbred with Denisovans more than 200,000 years ago, and Denisovans later passed traces of it on to humans. It shows up in people across Oceania and the Pacific islands.

In total, about 2% of modern human DNA comes from archaic groups.

We have never seen these ancestors' bones. But part of their DNA is in living people today.

The Trip Costs You Five Years. It Costs Everyone You Love Fifty.
Particles passing through you right now should never reach the ground. 🌌
Cosmic rays create them 15 km up, and they last two millionths of a second, barely enough to travel 600 meters. They reach the ground anyway, because at nearly light speed their clock runs slow.
The same rule works on people. Five years on a ship at that speed, and you come home to an Earth fifty years older.

Scientists discovered a spider that builds a catapult out of silk and fires ants into its web.

It was found in the rainforests of northern Queensland, Australia, near Cooktown. Researchers at Macquarie University call it the ballista spider, after the giant crossbows used in ancient warfare.

The spider spends up to 4 hours building its trap. It pulls 15 to 60 strands of silk tight into a cone shape, loading it with tension like a spring.

Its target is the green tree ant, an aggressive ant known for its painful bite.

When an ant bites the cone, the trap releases. The ant is flung more than 30 centimeters into the web, with acceleration above 1,300 meters per second squared.

A biomechanics expert said its instant power is greater than any other known silk-based biological catapult.

The spider uses the ant's own bite to fire the trap.

Nature invented the catapult long before humans did.

Orcas were filmed ramming a giant sunfish so hard that it burst into thousands of pieces.

It happened in the Gulf of California. The sunfish was a sharp-tail sunfish, a species that can grow longer than 3 meters and weigh up to 2,000 kilograms, as heavy as a car.

The sunfish was already dead. One orca gripped it by the tail fin and held it in place. A second orca charged in at high speed and smashed into it.

The holding orca let go right before impact, and the carcass exploded into thousands of fragments.

Researchers recorded it twice, in July 2024 and again in September 2025. Afterward, the young orcas ate the smaller pieces and the adults ate the rest.

Ramming has never been recorded before as a way orcas handle food, and it has only been seen with this one kind of sunfish.

Scientists have three ideas about why. The adults may be breaking food into bite-sized pieces for their young. Breaking it apart might also release nutrients. Or, since orcas are known to play with their food, it could partly be play.

Either way, it shows a level of teamwork most people never imagine in the ocean.
